CAN-END-LINING MACHINE.

Specification of Letters Patent. Patented J une 22, 1920.

Application filed March 1, 1916. Serial No, 81,315.

To all whom it may concern:

Be it known that I, CHARLES W. GRAHAM, a citizen of the United States, residing in Huntington, in the county of Suffolk and State of New York, have invented a new and useful Improvement in Can-End-Lining Machines, of which thefollowing is a specification.

This invention relates in general to can end lining machines and has more particu-' lar reference to can end lining machines which apply a previously cut out or formed liner to the canends. It will, however, be manifest, as the invention is better understood, that numerous features of it may have valuable application in can end lining Inachines wherein the liners are cut and applied in the same machines or as closely successive operations. Can end liners are frequently of fibrous material such as paper and in the form of delicate rings of large diameter which are easily distorted or torn in handling, and a mechanism to operate upon them effectively should be deliberate and certain in its action. YA principal object of this invention is the provision of a can end lining machine whereinthe operation of the individual parts of the machine may be relatively slow and unhurried and the machine at the same time have a relatively high capacity.

A further object of this'invention is the provision of a can end lining machine which is capable of moving the liners through. an opening above the liner seat in the can end which is smaller than the liner, so that the machine may be used with can ends in which the annular seaming flange extends inwardly over itself slightly as is sometimes desirable.

A further object of provision in such a machine of means for accurately and positively taking a canend and a can end liner from separate stacks and which, after depositing them in proper relative positions, will assemble'them into a unitary article. a

A still further object of the invention is the provision of such a'machine consisting of few and simple parts and adapted to operate upon a number of can ends simultaneously. 7

Other objects and advantages of themvention will be apparent as it is better understood from the following description the invention is the when considered in connection with the accompanying drawings illustrating a preferred embodiment thereof.

Referring to the drawings,

Figure 1 is a vertical front view of amachine embodying this invention;

Fig. 2 is a side view looking at the right hand side of Fig. 1;

' Fig. 3 is a vertical sectional view taken on the line 3 -3 of Fig. 1 and looking in the direction of the arrows;

Fig. 4 is a horizontal sectional 'view taken along the line 4+4 of Fig. 1', showing the multiple arrangement of the machine;

Fig. 5 is a horizontal sectional view taken along the line 5-5 of Fig. 3 and looking in the direction of the arrows, with parts broken away to more clearly show underlying parts; the right side of the view showing the cut ring and-can end feed slides moved to their inner positions;

Fig. 6 is an enlarged vertical sectional view taken on line 66 of Fig. tlooking in thedi'rection of the arrows and showing the ring chute, cut rings therein, and the recessed reciprocating feed slide for feeding the rings from the ring chute to the assembling station;

Fig. 7 is a vertical sectional view taken on line '7-7 of Fig. 4 looking in thedirection of the arrows,'andshowing an assembling plunger, a cut ring can end liner, and

a can end, all in assembling position, the

assemblingplunger having descended into contact with the ring, a further downward movement resulting in pushing the flexible can end liner past the annular shoulder on which it rests, down into the recess of the positioned can end;

' Fig. 8 is a vertical sectional view taken along line 8-8 of Fig. 1 showing in detail the mechanism for effectii'ig the discharge of the completed and lined ends;

Fig. 9 is an enlarged detail section showing a ring liner seated in the liner-slide;

Fig. 10 is a similar view showing it entering inthe liner-receiving groove in the can side by side and in a straight line, four being chosen for the purpose of illustrating this invention. At one side and parallel with the assembling stations is arranged a plurality of vertical can end stacks under which reciprocates a feed slide which automatically takes four can ends from these stacks and positions them simultaneously at the assembling stations, one at each station. At the opposite side and parallel with the assembling stations is arranged a plurality of vertical stacks of cut ring liners under which a feed slide reciprocates, which feed slide automatically carries four ring liners and positions them at the assembling stations directly over and in vertical alinement with the previously positioned can ends.

\Vhen thus arranged the slides are quiescent while a plurality of assembling plungers move against the ring liners and push them vertically downwardly into the linerreceiving recesses of the can ends. As these plungers retreat the slidesireturn for subsequent charges of'can ends and liners and as the plungers reach the end of their upward or retreating stroke the supports beneath the lined can ends are withdrawn, permitting the can ends to be dropped upon a conveyer carrying them out of the machine. The foregoing brief description applies, however, only to the machine shown on the drawing, which, may be varied in many ways without departing from the scope. or spirit of the invention.

Referring to thedrawings, reference characterA indicates what may be termed the main frame of the machine. This frame comprises suitable standards or legs a supporting a bed a From thisbed a standard a extends upwardly from each side and provides a bearing a for a power shaft B having at one end a driving pulley 6 through which is transmitted the power necessary to the operation of the machine.

Feeding. mechanisms are provided to feed the can ends and the can end liners simultaneously and in a horizontal plane to an assembling station where the liners are placed in the can ends. Two slides C and D are mounted upon the upper face of the bed and move toward and from each other in the operation of the machine. One of these slides, D, carries can ends and theother, C, can, end liners into assembling position. The liners E and the can ends F are taken respectively from stacks held in stack supports formed of vertically extending rods 7 e and vertically extending plates. 7 e

These stack supports are secured upon and extend upwardly from a plate G mounted above the bed a suflicient distance to permit the slides to move just under it. The rods 0 f and'plates e f are in number and arrangement such as to constitute four. stack supports for can endstacks f at one side and four stack supports for can end liner stacks e at the other side. The plate Gr is provided with four apertures g beneath the can end supports, in which apertures the bottoms of the stacks of can ends repose in position to have the lowermost can end of each stack removed by the slide D as it advances toward the assembling station. Four similar apertures g are located beneath the stacks of liners and these stacks also extend into the apertures, so that the lowermost liner of each stack may be taken by its slide C to the assembling station. The slides C and D receive their power from the shaft B, and this through the medium of a cam 12 engaging a roller 6 upon-one arm of a bell crank Z) pivoted atb on a standard a" and having pivotally connected to its other arm two links 2') and. 72 The link Z) is connected to a bell crank which, through a link Z)", connects with the slide C. The link If is similarly connected through a bell crank b and link Z2 with the slide D, these link and bell crank mechanisms being. so arranged as to cause the slides to simultaneously move toward each other on their operative stroke and back away from each other on their inoperative stroke.v

The assembling stations are located be tween the two series of stack supports and the slides are arranged and constructed so that the ring liner carrying slide C moves over the can. end carrying slide D at the assembling station.

The can end carrying slide D (see Figs.

5 and 7) is comprised in the present instance.

of a plate al having four semi-circular recesses d in its edge adjacent the slide C, each recess being adapted to engage a can end at the bottom of a stack when the slide is moved in its operative stroke. The slideD moves upon the bed a and. is provided with four tongues d3, one extending out and from beneath the center of each recess, these tongues being adapted to provide a positive support for the can end. The slide C, which carries the can end liners, (see Figs. 5 and 6) consists of a plate having fourapertures 0 each adapted to select the bottom-most liner of an appropriate stack and carry it forwardly over a can end carried by a recess (Z and tongue (Z Each aperture 0 is of size at its top equal to the over-all diameter of a. ring liner. An inwardly extending lip or flange 0 is provided in each aperture 0 a distance beneath its top equal to the thickness of a. liner, so that single liners may be selected by, the slide as itstarts movement on its forward stroke. The flanges 0 extend inwardly only a slight distance and beneath them the diameter of the aperture is equal substantially tothe outer diameter of a ring liner. Viewing Figs. 5 and 7 it will be noted that the bed. a? is cut away to provide guidewaysa for the tongues dfland the slide (1, which is much thicker than the slide D, is cut away at one side at 0 to permit the plate 03 to enter beneath it and position four can ends Fin vertical axial alinement respectively with the four recesses c and the rlng liners E carried upon the inwardly extendlng flanges 6 thereof. When the slides have arrived thus at the assembling station the cam 6 plunger comprises a head if and a stem h secured in a socket W in the cross-headh Outside diameter of the plunger head It is somewhat smaller than the diameter of the opening through the flange 0 1 When the slides have reached their inner position and are at rest, each plunger moves down-' wardly and engages the ring liner carried by the slide (3 and forces it past the flange 0. It carries it on downwardly to the can end beneath it and forces it past the upturned edge 7' of the flange 7? on which the liner seats, as will be later described more in detail. Thereafter the plungers move back out of the slides and the slides separate and return to receive a succeeding set of can ends and can end liners, leaving the lined can ends at the assembling station. An aperture a is provided through the bed beneath each can end, and through this aperture the lined can ends are discharged. Prior to their discharge, however, and in order that they may drop accurately through the apertures, two bars Z and-Z acting under pressure of springs s extend across the machine in recesses a and a therein, these parts closing the apertures a to .a suflicient extent to prevent the can ends dro 'iping through. As the plungers reach the upper end of their stroke the bars Z and Z are caused to move apart bya pair of wedge blocks Z (see Figs. 5 and 8). Each of these wedge blocks is carried on the'end of a stem Z secured in a socket Z in the cross-head, and only when the cross-head is in the uppermost position are the larger parts of the wedge blocks moved between the bars Z and Z to separate them. As the plungers near the top of their stroke, the bars Z and Z are moved apart and the can ends drop upon a conveyer M which carries them outside the machine. The can end shown on the drawing is provided with a shoulder f flaring outwardly slightly from the central part of the can end to the liner seat, and the internal diameter of the liner is preferably less than the largest diameter ofthe shoulder. The plunger will wedge the linertightly and positively in place by forcing it downabout this tapering shoulder. The edge of the liner is bent back to passthe edge f of the peripheral flange of the can top (Fig. 10) but not sufficiently to prevent its springing back to its original position as it approaches its seat. Where the liner is wedged down tightly about the shoulder of the can end or its forward edge is disposed behind the edge f or both, the liner is prevented from being displaced in handling or in transferring the can end from the liner applying machine to a machine for applying it to a can body forming a unitary article.

It will be manifest from the foregoing that the machine may be constructed to operate upon any number of can ends simultaneously and any desired capacity therefore given it without increasing the time of operation required for the placing of a liner in an individual can end.

It is thought that the invention and many of its attendant advantages will beunderstood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts Without departing from the spirit and scope ofthe invention for sacrificing any of its material ad vantages, the form hereinbefore described being merely a preferred embodiment thereof. 1
